1 Claim.

This invention relates generally to receptacles and more particularly toVmilk-safes or receptacles for the keeping of milk or other articles ofa similar nature. Y

Among the objects of the present invention is the provision of structureadapted to act as a deposit and collection receptacle for use with allmanner of articles which may be delivered at the home or oice or takentherefrom when the place is unattended, yet -will prevent unauthorizedtampering or theft. Y

Another object herein lies in the provision of a novel receptacle whichmay be used as a convenient carrier to transport the delivered articlesfrom the threshold to some other point, as for example to therefrigerator in the dwelling.V

A further object of the present invention lies in the provision of novelmounting structure cooperating with the new receptacle so that thereceptacle is readily put in place and automatically locked by a simplesingle operation.

A feature of the present construction permits the receptacle to bereadily'unlatched lby lthe proper person evenwhen the receptacle isfully loaded.

Another feature of this invention lies in the fact that there issubstantially only one mov-ing part, and this is adequately concealedandvprotected so that picking or tampering are` discouraged andprevented; no hinged parts or moving doors on the receptacle beingutilized.

Another object of the present invention lies inthe novel construction ofthe receptacle and the mounting structure therefor, wherein the channelmember for cooperation with the mounting structure is formed integrallywith the -receptacle and is fabricated at the same time. In accordancewith the present invention, the receptacle and the mounting structureare preferably formed up from sheet metal stock. The invention thus byreason of novel design land organization of the various parts permitseconomical large scale production with consequent wide distribution.Large door delivery service organizations such as dairies, and bakerieswill find the present receptacle and mounting highly charactersdesignate corresponding throughout the several views, in which:

Figure 1 is a view in perspective as seen from the outside of thebuilding, or outside of the door, showing the receptacle in engagementwith the mounting means or structure.

Figure V2 is a view in elevation as seen from the inside of thebuilding,for inside of .the doorway, showing the receptacle inengagement with the mounting'means, and the door swung partially openthrough degrees.

Figure 3 is an elevational viewk showing the receptacle in engagementwith Vthe mounting means, as seen from the outside side or wall thereof.

Figure 4 is an elevational view showing the receptacle in engagementwith `.the mounting means, as seen from the inside wall or side thereof.This gure is a rear viewof Figure 3.

Figure 5 is a horizontal sectional viewlenlarged) of Figure 4 as seenfrom the plane 5-5 thereon. y

Figure 6 is an enlarged sectional view showing in detail the lower righthand vcorner portion of Figure 5. y Y

Figure 7 is an end elevational view of the receptacle, that is to saythe' end containing the latching mechanism, the right hand end in Figure5. In this gure the handle/ member is broken away, and the scale isreduced from Figures 3 and 4. Y

Figure 8 is an elevational view of the mounting structure, as seenfrom'theleft in Figure 5. The scale is the same as Figure 7,

Figure 9 is a fragmentary view in perspective parts (enlarged) showingin detail `the upper left hand Y corner of the 'mounting lstructure asshown in Figure 8.

The receptacle generally indicated b y numeral I0 comprises a bottom II,a topjl2, an inside or' front wall I3, an outside or rear wall I 4, acurved end wall I5, a channelled end wall I6, and a handle member I1.`The front wall I3 is provided with an Yaperture I84 having anindentation I9 facilitating manual access tothe handle element 31. Thebottom I I and theA top I-2rare substari tially identical in `size andconfiguration and are secured in any suitable manner, for example bysoldering, to the lower and upper edgesrespectively of the sing-le metal-sheet generally indicated 'by numeral 20. The sheet `2Il is suitablyfolded and formed to Yhave the several portions which are the front wallI3, the curved wall I5, the rear wall I4, the channels 2l and 22 whichare lintegral-'withthe -end'wall I6. AThe handle member I1 is suitablyaflixed to the top I2 at the points 23 and 24, as for example bysoldering.

The manner in which the sheet 20 is folded and formed is best seen inFigures 5 and 6 of the accompanying drawing. In accordance with thepresent construction the single sheet 29 begins at one edge of theaperture I8 with the portion 43 and extends completely around thereceptacle I to terminate with the portion 44 at the other edge of theaperturev I8. This construction permits economies in manufactureandresults in a strong seamless wall. The indentation I9 may be of anysuitable configuration to permit ready and convenient access to thehandle element 31I "'15Y -ality of right angle bends 48, 49 and 50resulting While the wall I3 is shown having an aperture- I8 of such sizethat the wall is in effect dividedY meansgenerally indicated by numeral82, this is preferably formed from a single sheet of material which isformed by bending same into shape. This construction permits the use oflighter material with consequent reduction in cost of material and incost of manufacturing. The mounting means is provided with twooppositely disposed channels 45 and 46, the configuration of which isbest seen in Fig. 6 of the accompanying 10 drawing in .which one of thechannels, namely,

.-of one will suce for both. As seen in Figure 6,

fthe body 41 of the mounting means has a pluin the channel 45 which isof substantially U- into wall portions 43 and 44, it will, aof course,N'

be obvious to those skilled in the'art to'which the present inventionpertains, that such aperture '2'0 corresponding right angle bends 48',49', and 50'.

may be made of any size suitable to allow the' passage therethrough ofthe articles forrwhich the receptacle I0 is to be'used.' Since .thechannels 2I and 22 are lsubstantially identical-but oppositely directed,a detailed :description of=one will suffice for both. Fromthe startingpoint at shaped formation having the open portion of theUxfa'cingztowa'rd the inner surface of the body 41. In Figure 9, thechannel 46 is shown having The upper portions of both of the channelmembers 45 and 46 are cut away-to form `angularly and ,downwardlydirected entrance edges 5I and 52 including portions 53, 54, 55 and.AThe pur.-

5 pose of the entrance edges 5I and 52 is to facilitate the extreme leftthe inside orfront wall continues b to the right as seen in Figure 5,and this wall I3 makes a right angle bend at 25, outwardly. Continuingoutwardly another right angle bend v is made so that the sheet materialnow travels to.-` ward the curved end I5 tothe 180 degree bend 21.Continuing toward lthe 4,wall I6 the sheet 29 makes a right anglebend 28so that it travels inwardly of the receptacle I0 thus forming the wallI6. The wall I3 is of course provided with the complementary bends 29and 30 so that the channel 2| is offset inwardly with relation to thereceptacle I0; while the wall I4 is similarly provided with thecomplementary bends 3| and 32 so that Athe channel 22 is inwardlyoffset.

The inward offset of the channel 2I allows the' receptacle I0 to beplaced close to the door `8| so that the wall I3 may be ushtherewithwhen the receptacle ID is locked within the mounting structureor means generally indicated by nu. meral 82. The inward offset of thechannel 22 permits the mounting means tobe narrower than the receptacleI0 with acorresponding reduction inweight andcost. 4 y y j lThe lowerportion VVof the channelled end wall I 6 is provided with a rectangularorifice 33 v.to permit the latching element 3 4 to oscillateabout thePivot formed by the-rivet pin 35 mounted in and projecting verticallyupwardly from; the bottom II. The latching yelement 34 is substantiallyV-shaped having the forward end thereof suitably rounded and beveled asis we ll known -in the art to permit the said element to cooperate withthe latching plate 36 on the mounting means 32. The latching plate 3 6has .the upper portion thereof curved toward the inner surface of thebody 41. The innerend of the latchingmember is provided with avertically upwardly projecting integral handle element 31; The latchingyelement 34 is maintained in operative; positionV by means of acontractile coil spring38. Spring 38 resiliently connects arm 39 of thelatcliirrgele-A ment 34 by penetrating an orifice 49 inY arm ,39' withpin 4I on bottom II, kA stop 42 mounted upon the bottom II serves tolimit vthe forward movement of the latching element 3 4, while reartherapid and convenient insertion of the lower corners 51 and 58respectively of the vchannels 2I a11d 22. .i

The lower edge ofthe body 41 of the mounting means 82 is provided with atab of metal which is orifice 60 adaptedto receive and engage thelatching element 34. o

The mounting structure or means is provided with a plurality vof,suitable orifices 6I which may be utilized. forrthe penetration ofscrews Yorgother 45 devices to secure the mounting means 32 to the doordamn 62.

While the spacing ofthe channels 2|, `22,' and 45 and 46 Awith relationto eachother has been slightly exaggerated in Figures 5 and 6, this hasbeen for-thepurpose of clarity inthe l drawing and vit will beunderstoodA that only sufficient clearancejshould,be allowed between-theparts to permit the same to rest and slide within' one another..Obviously, thedevice may be given anydesired protective coating such aspaint o r jamb 62 by means of screws (not shown) Vthroughenamel, or'thesame maybe madeof a non-- corroding metal.A I' I l OPeTaFm L? f l Themounting means 82- is secured to the door the holes 6I with the loweredge .thereof resting 'on the step 66. 'I'hemounting means l2- may be'fastened to either'of the door jambsand'it-is found moreconvenienttof-place'itl on the oneV near the' hingedv edge of the'door.AThe receptacle wardmovement of the latching elementg34-is I0fis"preferably kept during the daytime near the refrigerator Within thevdwelling and after the milk has been consumed, the bottles .'65 areplaced within the Yreceptacle III throughV the aperture I8. There'ceptaclejs manuallycar'ried by neans ofthe handle I 1 to thedoorstep- 66 and is rested thereon. The milk man -indeliv'ering filledbottlesV merely removes v the` empties tles. Lower corners 51 and 58 ofthe channels 2| and 22 are placed within the upper portion of themounting means 32 in contact with the inner surface of the body 41.Since the channels 45 and 46 have been cut away at the upper portionthereof as has been previously described, and since the greatest widthof the wall I6 is slightly less than the distance between the entranceedges l and 52, this insertion is rapidly and smoothly accomplished. Thedownwardly and angularly directed portions 53 to 56 inclusive facilitatethis operation. The handle member I1 is then lowered and with it, ofcourse, the receptacle ID until the latching element 34 strikes theupper curved surface of the latching plate 36. The latching element isforced inward by reason of the cam action of the curved surface of thelatching plate and as soon as the latching element 34 and the orifice 60are aligned, the element 34 is pulled outwardly by spring 38 so that thereceptacle I0 becomes locked in place. Since the wall portions 43 and 44are in contact with the lower portion of the door 8|, it is impossibleto remove the bottles 65 from the container l0 while the door 3| isclosed. It is, of course, a simple matter to open the door 8l away fromthe device lll, which will then appear as seen in Figure 2. A quickmanipulation of the handle element 3l will release the latching element34 and the whole receptacle I0 may be removed by means of the handle l1and transported with the bottles 65 to the refrigerator or other place.

When the spring 38 is of low tension construction, the latchingoperation will occur merely by reason of the weight of the receptacle I0and.

the bottles 65 pushing downwardly. If desired,

however, the spring tension 38 may be increased so that in addition tothe weight of the receptacle I0 and the bottle 65, a manual pressurewill be required in order to actuate the latching element. In the lattercase instead of merely resting the container I0 on the door step 66, thechannels 2l and 22 may be inserted within the upper portion of themounting means `32 and the container I0 will be supported off thesurface of the door v of lightness in weight, economical construction, ahigh degree of convenience and facility yet which is tamper andtheftproof.

The foregoing description has been made rather detailed for clearness ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, but the appended claim should be construed as broadly aspermissible in view of the prior art.

I claim:
